1. A call processing system for mobile communication terminals, comprising: a gateway location register configured to generate a Database (DB) for international roaming service subscriber; and a roaming control unit configured to register a location of a mobile communication terminal, to determine whether a call originates using a primary number (primary No.) or a secondary number (secondary No.) in the international roaming service on a basis of originating service provider information and a called number, included in a call origination signal from the mobile communication terminal, and to send a signal corresponding to a result of the determination to a mobile switching center of a network in which the mobile communication terminal is located, wherein the international roaming service assigns the primary number in a home network and assigns the secondary number in a partner network; and wherein when the mobile communication terminal is located in the partner network: the gateway location register acquires a subscriber profile from a home location register in response to a location registration request signal received from the partner network and transmitting the subscriber profile to the partner network; the gateway location register receives an ack message from the partner network; and the roaming control unit updates the location information of the subscriber on a basis of the ack message received from the partner network.
A mobile call processing system manages international roaming by using a gateway location register to store subscriber data. When a mobile device roams, the gateway location register retrieves the subscriber's profile from their home network and sends it to the visited network. After successful registration, confirmed via an acknowledgment message, a roaming control unit updates the subscriber's location. The system determines if a call originates from the device using either its home network number (primary) or the visited network number (secondary) based on originating service provider info and dialed number. A signal reflecting this determination is sent to the local mobile switching center.
2. The call processing system according to claim 1 , wherein the mobile communication terminal originates a call by attaching a special prefix to a called number when originating a call using a number of some other network.
In the mobile call processing system described in claim 1, when a mobile device makes a call using a number from a different network, the user prepends a special prefix to the dialed number. This prefix signals to the system that the call should be routed using the other network's number.
3. The call processing system according to claim 1 , wherein the mobile switching center includes a Mobile Subscriber Integrated Service Digital Network (MSISDN) number for the mobile communication terminal's own network, and sets a calling number as the MSISDN number of its own network with respect to an originating call from the mobile communication terminal.
In the mobile call processing system described in claim 1, the mobile switching center, which handles calls for the mobile device's home network, sets the calling number for outgoing calls to the mobile device's home network number (MSISDN). This ensures that the call appears to originate from the user's primary number, regardless of the network they are currently using.
4. A call processing system for mobile communication terminals for providing international roaming service using a primary number assigned by a home network and a secondary number assigned by a partner network, comprising: a roaming control unit configured to determine whether a mobile communication subscriber has subscribed to the international roaming service when a call to the secondary number is received from a gateway mobile switching center of the partner network, and to generate a text message indicating reception of the call to the secondary number if it is determined that the mobile communication subscriber has subscribed to the international roaming service; a location register configured to provide information about a location of a terminal of the mobile communication subscriber on a basis of the primary number corresponding to the secondary number; and a message sending unit configured to send the text message received from the roaming control unit to the mobile communication subscriber terminal on a basis of the location information of the mobile communication subscriber terminal received from the location register, wherein the roaming control unit determines whether the mobile communication subscriber has subscribed to the international roaming service when the roaming control unit of the home network receives a Send Routing Information (SRI) signal for the secondary number from a gateway mobile switching center of the partner network.
A mobile call processing system provides international roaming with primary and secondary numbers. When a call arrives at the visited network's gateway mobile switching center directed to the user's secondary number, a roaming control unit in the home network checks if the user has international roaming enabled. If so, it generates a text message confirming the call to the secondary number. A location register then provides the user's device location based on the primary number. Finally, a message sending unit sends the text message to the user's device at that location. The roaming control unit makes this determination when it receives a Send Routing Information (SRI) signal for the secondary number.
5. A call processing system for mobile communication terminals for providing international roaming service using a primary number assigned by a home network and a secondary number assigned by a partner network, comprising: a roaming control unit configured to determine whether a mobile communication subscriber has subscribed to the international roaming service when a call to the secondary number is received from a gateway mobile switching center of the partner network; a location register configured to determine a location of a terminal of the mobile communication subscriber on a basis of the primary number corresponding to the secondary number if it is determined by the roaming control unit that the mobile communication subscriber has subscribed to the international roaming service, and to request and to receive a mobile station roaming number from a mobile switching center of a network in which the mobile communication subscriber terminal, the location of which is determined, is located; and a gateway mobile switching center configured to receive the mobile station roaming number transmitted from the location register and to provide reception of the call to the secondary number to the mobile communication subscriber terminal on a basis of the received mobile station roaming number, wherein the roaming control unit determines whether the mobile communication subscriber has subscribed to the international roaming service when the roaming control unit of the home network receives a Send Routing Information (SRI) signal for the secondary number from a gateway mobile switching center of the partner network.
A mobile call processing system supports international roaming using primary/secondary numbers. When a call to the secondary number is received at the visited network's gateway mobile switching center, the home network's roaming control unit determines if the user has subscribed to international roaming. If subscribed, a location register finds the device's location using the primary number, requests a Mobile Station Roaming Number (MSRN) from the MSC serving that location, and receives the MSRN. The gateway mobile switching center then uses the MSRN to route the call to the user's device. The roaming control unit determines roaming subscription upon receiving a Send Routing Information (SRI) signal for the secondary number.
